本文在句法层面上对“SOV+吗?”是非疑问句的生成和受事(宾语)前置的过程进行了描述,探讨了这一变体的产生是话题化的结果,其根本动因在于说话人意欲强调或突显的重点信息;同时,我们还从语用和语义角色的角度探讨了受事(宾语)前置语言类型学之外的两个限制条件:其一,受事(宾语)的话题化受制于语境与场合,需要语用推理的介入;其二,在“SOV+吗?”是非疑问句中,S和O的确定取决于动词配价,其中受事起决定作用。 On the syntactic level, this article describes the process of the formation of non-interrogative sentences and the antecedent of objects (objects) in “SOV +?? ”, And discusses the production of this variant as the result of topic-orientedness. At the same time, we also discuss two limitations beyond the typology of pre-linguistic (object) precepts from the perspective of pragmatic and semantic roles: First, the subject (object) Topic is subject to the context and occasion, which requires the intervention of pragmatic reasoning. Second, in the question of non-interrogative sentences, the determination of S and O depends on the valence of the verb, in which the affair plays a decisive role.
